TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,522, dated November 3, 1896.

. Application filed November 16, 1889. Serial No. 330,588. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY H; UNZ, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Type-Writers, of which the following is a true and exact description, due reference being had to the drawings which accompany and form a part of this specification and in which similar letters denote similar parts.

My invention relates more specifically to devices adapted to guide the material which is to be written upon while it is being placed around the platen; and it consists in a device secured to the machine which can be moved into such a position with reference to the platen that when the paper, envelop, &c., is being placed around the platen said paper, envelop, &c., can be so placed without lifting the platen and fed continuously and properly into its position with reference to the platen.

WVhile my improvement is well adapted for use with any character of paper, it is especially applicable for use with paper or envelops which are of less width than the platen itself, as when envelops or paper of such a character is placed upon the platen in the mannernow in ordinary use it is often passed around the platen unevenly, and in order to cause it to lie properly it is necessary to lift the platen and straighten the paper or e11- velop.

In the drawings, Figure l is a front View of platen, platen-carrier, frame or bracket, and paper or envelop guide. Fig. 2 is a section on line a: 00, Fig. 1, showing paper or envelop guide out of action; Fig. 3, the same section as Fig. 2, showing paper or envelop guide in action. Fig. 4: is a front view of paper or envelop guide, illustrating the method of removing the metallic strips of said guide. Fig. 5 is a side elevation of frame carrying paper or envelop guide. Fig. 6 is a detailed view of rear elevation of frame or bracket carrying the metallic strips of paper or envelop guide. Fig. 7 is a side elevation of the metallic strip of paper or envelop guide.

A represents the platen.

Bis the rod of the platen-carrier frame. To this red, by means of the thumb-screw b,

is adj ustably attached the frame or bracket (J. In this frame is the slot 0. The slot 0 in the frame or bracket extends in a direction generally circumferential of the cylindrical platen, but, as illustrated, one portion of the inner face of the bracket at the point 0 is concentric with the platen, While the lower portion of said inner face of the frame at c is eccentric or at an angle to the platen. Movable in this slot 0 is the thumb-piece D. This thumb-piece is secured to the metallic strip cl. Soldered or otherwise properly secured to the metallic strip cl is the curved metallic strip cl. This metallic strip cl is secured to the strip d at a point near the end of said strip cl. A portion of this strip d extends up beyond the point of juncture between the strips 02 and cl. The thumbpiece D normally rests in the slot 0 in the position shown in Fig. 2, and when it is desired to insert a sheet of paper or envelop onto the platen the thumb-piece D is moved in the slot 0, carrying with it the metallic strips cl and cl. Vhen the thumb-piece D reaches the portion 0 of the inner face of bracket 0, it moves inward in a path eccentric to the platen, causing the strip cl to move against and beyond the printing-point of the platen or the lowermost point of the platen. The paper may be then inserted around the platen the lower portion of the strip d forming a point of reception for the paper and guiding it around the platen, past the printing-point, while the portion of the strip d which eX- tends above the juncture-point of the strips d and d guides said paper up around the platen. The paper is thus guided from its first point of contact with the platen until it is fully around the platen.

As generally used, after the paper is brought into position on the platen the thumb-piece D is pushed back again into the position shown in Fig. 2 and the paper is in the platen ready for the writing to begin, but in some cases where the printing is not carried over the whole of the paper, such, for instance, as in envelop-writing, the frame or bracket 0 is moved along the rod to a point where the printing is not desired to be done and the envelop or paper put in, as hereinbefore described, and in place of pushing the thumbpiece back into the position shown in Fig. 2

it remains in the position shown in Fig. 3 during the operation of writing. This is especially applicable to paper which is of less width than the platen and for envelops.

As illustrated in the drawings, there are two metallic strips d and d. The object of this is that there will be given to the strip d as much resiliency as possible and to make its point of spring as near its point of contact with the platen as possible, and also it is desirable that there shall be a strip projecting around the platen and between the platen and the frame or bracket 0, so that the paper will not strike the frame or bracket Oin pass ing around and will be guided through a greater period of its passage around the platen than if only one metallic strip were used, but I do not intend to limit myself to the use of two metallic strips, as one metallic strip may be used and great benefit derived from the same.

In order to remove the metallic strips d and (1 when they become worn, so that they may be replaced, the thumb-screw D is turnedinto the position shown in dotted lines, Fig. 45, when the thumb-piece and metal strips may be removed from the frame and replaced by others.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

1. In combination, a platen, a paper-guide, and a bracket on which said guide is adapted to move in a path eccentric to the platen to and over the printing-point on said platen.
